v ARTHUR L. PALMER, OF CHENANGO FORKS, NEW YORK.

COMBINED MILK SIIERER AND AER-ACTOR.

To all whom it may concern ie it known that l, ARTHUR L. PALMER, acitizen of the United States, residing at Chenango Forks, in the countyof BIOOIHQ and State of New York, have invented certain new and usefulImprovements in Cour bined Milk Stirrers and Aeratin's, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to improvements in combined milk stirrer andaerator.

The object of my invention is to provide a simple, cheap and effectivedevice of this character in which the milk can be more thoroughlystirred and aerated without removing it from the cans in which it isshipped or stored.

In the accompanying drawings Figure l, is a vertical sectional view ofthe ordinary milk can showing my device in operation. Fig. 2, is anenlarged vertical sectional view of my improved stirrer and aeratorshowing in detail the handle attaching means. Fig. 3 is a horizontaltransverse sectional view of Fig. 2.

Referring now to the drawings 1 represents the body portion of myimproved stirrer and aerator and which is of an inverted truncated coneshaped, open at its lower end as indicated at 2. The upper end 3 of thebody portion is provided with a central opening a through which passesthe lower end of the handle 5. This handle may be of any desired formbut preferably of that form shown in the drawing and has its lower endscrewthreaded as indicated at (3 and screwed thereon above and below theupper end 8 of the body portion are nuts 7 and 8, whereby the handle isrigidly and yet removably held on the body portion. This specific meanscould be varied without departing from my invention but a re movablehandle enables the body portion to nestle one within the other forpacking and shipping and the handles can be separately packed thussaving considerable in the crating and shipping of the devices.

The truncated cone shaped body portion is provided with a series ofopenings 9 a short distance from the upper closed end and are arrangedaround the periphery thereof, and are for the purpose of allowing theair to pass outwardly as the device is forced down through the milk orliquid causing the same to be more thoroughly Specification of LettersPatent.

aerated as will be hereinafter more fully described.

The lower end of the truncated cone shaped body portion is provided withan outwardly extending flange 1O entirely surrounding the same. Thisflange is shown of a considerable width and causes a greater agitationof the milk or liquid as the device is raised and lowered through theliquid and which greatly aids in the aeration of the milk or liquid.

Applicant is aware that receptacles have been used to force air intoliquids to aerate the same but such receptacles do not have the handlesecured to the center thereof nor do they show the outwardly extendingflange for causing a greater agitation of the liquid and necessarily amore thorough aeration of the liquid.

In operation my improved device is placed in the can or other receptaclein which the milk to be aerated is held and when the lower end of thetruncated cone shaped body portion enters the liquid the air therein isprevented from passing outwardly around the lower end thereof. Thecontinued downward movement causes the air within the truncated coneshaped member to be compressed by the liquid from below and forces theair out through the small openings and its passes upwardly through theliquid and aerates the same. The flange carried by the lower end of thetruncated cone shaped member necessarily causes a greater opening in theliquid in its upward and downward movement and therefore agitates theliquid to a greater extent and more thoroughly aerates the same.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

1. A combined stirrer and aerator comprising an inverted receptaclehaving openings adjacent its upper end, a handle and a flange carried bythe lower end and extend ing outwardly in a horizontal direction.

2. A combined stirrer and aerator comprising an inverted receptaclehaving openings adjacent its upper end, a handle carried by the upperend of the receptacle in the center thereof, and a horizontal flangecarried by the lower end of the receptacle at right-angles to thehandle.

3. A combined stirrer and aerator, comprising an inverted receptaclehaving openings adjacent its upper end, a handle secured to the upperend of the receptacle in the center thereof, and a horizontal flangecarried by the lower open end of the receptacle and extending at rightangles to the handle.

4. A combined stirrer and aerator, comprising an inverted conical-shapedreceptacle having openings adjacent its upper end and a central openingin its upper horizontal end, a handle having a screw-threaded portionpassing through said opening, a nut on said screw-threaded handle aboveand below the upper end of said receptacle and a broad horizontal flangecarried by the extreme lower end of thereceptacle and 15 entirelysurrounding the same and extending at right angles to the handle.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
